Test repository

ST is developing a test repository for SPC56x. The tests repository is the set of self tests for

a given SPC56x.

Figure 2.

Test repository

Self tests are functional tests downloaded into the RAM of the target MCU.

They are then executed using the debugger. The MCU must be put into bootstrap loader

mode to allow the JTAG tool to connect, load the self test, execute it, collect the results and

show them on the PC.

They include memory tests, CPU self tests and peripheral self tests.

Target connection

ST has developed a target connection tool with Raisonance. This tool is powered from the

USB port of the PC and connects to the JTAG port of SPC56x.
